Perhaps I should have said conclusive evidence with respect to the responsibility of the downing of the plane.
There is evidence but from our perspectives without means or sufficient knowledge to examine the data first hand and all this amid a propaganda war from both sides, I see little to make me confident enough to believe one side or the other. I am convinced that there are no clean hands and that I have no reasons to trust either side. Unfortunately I don't see any unbiased third parties with information either. In fact it seems the whole world is lining up on one side or the other.
The stakes are high and there are massive resources being brought to convince people using any means that their side is right. I do not rule out massive disinformation from both sides.
This is why I argue that we must be very disciplined in what we accept is true and how we interpret what little information is available. I refuse to be categorical about what I think is uncertain.
